Wow I feel comfortable speaking with you rather than other people in another website forum. You know some people like me, we appreciate the old stuff and we like to salvage anything that are still good. Some people would just suggest to purchase a new one instead of repairing the current one, even though it is still repairable.

So coming back to the topic, I find the original Apple SSD & OWC to be quite expensive and their performance are not as good compared to 970 Evo. So I will go for the Samsung one by using an adapter from Sintech.

There are some questions about the logic board that I have found in AliExpress, it states that their logic board are brands from MIXUSP, KEFU, Reboto. Are these companies making logic boards, or they just make those boards from scratch?

Now based on your opinion, would you prefer to buy from this site, or do you have any idea's on where to find a reliable board & website?

I also like to make re-use parts whenever possible. I have put together some Macbook Pros and Airs that wound up saving me a lot of money. My "franken Macs" have been gifted to relatives and friends for daily use.

I have never purchased a board from Aliexpress. I think the vendors are salvagers/refurbishers. Original Apple parts can only come from AASP. In Canada, authorized repair depots cannot sell OEM parts without installing them for the customer. It may be the same in the USA too.

I have purchased salvage machines from local buy-and-sell websites like Craigslist, Kijiji, and Letgo. Shipping from China to Canada can take up to 2.5 months. I recommend looking at eBay before Aliexpress since you will have purchase protection through PayPal.

I have heard about this information before, where most phone/laptop repair companies in USA & Canada could not simply refurbish or even repair Apple devices and Microsoft software. I heard it from Louis Rossmann.

As for know I am stuck, don't know whether to take the risk of buying a used board or just buy a used 2017 MBA. A used logic board is hard to find a reliable one. In my place where I live used MBA comes quite expensive and less options in SSD Capacity and i7 Processors.

@Audit13
That's nice to hear. Franken Macs? could you enlighten me about it?

I didn't come across the information about heat issues before, that is good to know. But I will maybe have to go with the Evo 970 as I have already purchased it.

Referring to the thread you showed me, I read the adapter company suggest to input this code into the terminal:Sudo pmset standby 0
Sudo pmset hibernatemode 0 standby 0

I don't know whether this works or not as I haven't tested it yet.

Franken Mac is a Mac I put together using different parts from different Macs, similar to the way Dr. Frankenstein put together his creation from different dead body parts.

The terminal command is necessary to prevent the Macbook from going into hibernation. Waking a 2013 or 2014 Macbook with a nvme drive from sleep mode can cause kernel panics. These panics require a hard reboot to get back into the OS. The terminal commands are not needed for a 2015 or 2017 Macbook because these models have no problem with waking up from hibernation.

I'm in a big city so there are lots of people selling Macbooks. I am patient and look for Macbooks with reusable parts. I have put together some really cheap Macbooks but it can take months to find all the right parts.

There is no difference between a 2015 and 2017 logic board except for a slightly fast cpu in the 2017. Finding a used 2015 board may be easier.

The CPU architecture is different but the physical connectors are in the same place.

I believe the original 2015 MBA models also came with 4GB RAM standard (8GB optional upgrade) and in 2016 8GB was made standard.
The base model i5 1.6ghz model was bumped up to an i5 1.8ghz in the 2017 models. The i7 2.2ghz option stayed the same in the 2015 and 2017 models.

Parts are definitely interchangeable. I’ve swapped stuff from my 2015 MBA to a 2013 MBA when testing out components. Works fine.
Your best bet would be looking for a 2015 board with 8gb of RAM. i7 would be a bonus, but not necessary IMO. I used to have a base 2015 13” 1.6 i5/4GB/128GB model that I picked up super cheap. Sold it when I found a nice deal on a 2015 13” 2.2 i7/8GB/512GB model that I’ve been using as my main laptop for awhile.
Not too much of a speed difference, but 4GB is a bit low as most (all?) macs come with 8GB (or more) standard now.
